Coming Soon
SKU
UNI-Dex5-1
High Precision, Ultimate Control
Each finger joint has degrees of freedom to support smooth backdrivability.
Eliminates "stiff hands", making operations smoother and more convenient for reinforcement learning(RL) training.
Ultra-fast Reflexes, Snake-like Flexibility
Number of degrees of freedom
20
5pieces
All five fingers can be replaced independently
±22° Four-finger Lateral Swing
Improved grip reliability and adapts more effectively to curved surfaces of grasped objects.
Micro-gap design ensures smooth and effortless motion
The rotation axis of joint is closer to the surface, with ultra-small joint gaps.
This enables a smoother and more fluid grasp, preventing joint corners from getting stuck on objects.
